3. The Float Collar Is Too Close To The Water Tank

If the float collar is too close to the water tank, it may be rubbing against it and causing the sticking problem. To resolve this, you can adjust the position of the float.

Also, if the float is old and breaking down, it may lose its buoyancy or become misshapen, causing it to stick. In this case, it’s advisable to replace the float altogether

Solutions:

i) Adjust The Collar Of The Float:

Step- 1: Turn off the water supply to the toilet by turning the shut-off valve located behind the toilet clockwise.

Step- 2: Remove the toilet tank lid by lifting it straight up or unscrewing any bolts that secure it in place. Set the lid aside in a safe location.

Step- 3: Look for the float assembly, which includes the collar, float arm, and float ball or float cup. It is typically attached to the fill valve or connected to the flush valve inside the toilet tank.

Step- 4: Depending on the specific design of your Kohler toilet, there may be different methods to adjust the float assembly. Here are two common adjustment methods:

• Float Arm Adjustment:

Look for an adjustment screw or clip on the float arm. Loosen the screw or release the clip, and then slide the float arm up or down to change the position of the float assembly. You can lower the float assembly to increase the water level in the tank or raise it to decrease the water level. Make small adjustments until you achieve the desired water level.

• Float Collar Adjustment:

 Some float assemblies may have a sliding or rotating collar that allows for vertical adjustment. Check if the collar can be moved up or down along the float arm. Adjust the collar’s position to change the height of the float assembly and thereby adjust the water level.

Step- 5: Once you’ve made the necessary adjustments to the float assembly, turn the water supply back on by rotating the shut-off valve counterclockwise. Allow the tank to fill, and then flush the toilet to check if the float no longer sticks and the water level is at the desired level.
